Horizontal Pumps


The Strongest, Most Versatile Horizontal Pumping System in the World

Have any questions? Let Us Know.

Our laser alignment precisely aligns the motor and thrust chamber prior to the function test. This ensures the unit operates with low vibration, extending the life of the unit.

The Summit ESP horizontal surface pumping system is an efficient alternative to positive- displacement, split-case and other surface pumping options. The system design is based upon proven ESP pumps already in use in thousands of downhole applications. The multistage centrifugal pump is mounted securely on a modular skid, powered by a 2-pole motor, and protected by a robust thrust chamber.
